The A's beat the Mariners 10-2, but the ugliness wasn't because of the lopsided score, a beaning, a brawl or anything else that happened during the game. This one was due to the outdated O.co Coliseum.

The San Francisco Chronicle's Susan Slusser explains:

#Athletics need a new stadium: a flood on clubhouse level means both teams showering in Raiders locker room.

The O.co is the home for both the Athletics and the NFL's Oakland Raiders, and it is safe to say that both franchises would like a new stadium.

The O.co, formerly Oakland Alameda County Coliseum, opened in 1966. It cost $25.5 million to build. It did undergo renovations in 1995 and '96, and the bill for that work ran up to $200 million. Those changes were made as part of deal to usher the return of the Raiders to Oakland.
